x86: soften multi-BAR mapping sanity check warning message
Impact: make debug warning less scary The ioremap() time multi-BAR map warning has been causing false positives: http://lkml.org/lkml/2008/12/10/432 http://lkml.org/lkml/2008/12/11/136 So make it less scary by making it once-per-boot, by making it KERN_INFO and by adding this text: "Info: mapping multiple BARs. Your kernel is fine." Signed-off-by: Ingo Molnar <mingo@elte.hu>
